This file is on the subject of 30 Megabytes, ensuring that the complete download of the software is completed before stepping to the software installation. If needed, we can move this file to a different location which is likely more permanent for python installation.

Step 3

Below are the instructions for installation of python:

From the installed location, click on the below icon python-3.7.4-amd64.exe. Clicking on this icon pops up the installation dashboard for python. This dashboard is also called as the python setup pop up window, and a snap of the same is pasted below; this snap is for the popup window version python 3.7.4. Make sure that the below-enlisted checkboxes are checkered in at the installation setup popup.

  • ” Install launcher for all users (recommended) “
  • ” Add Python 3.7 to PATH  “

In the case where we have an existing version of Python already installed in our system, then the message in the command prompt stating Install now will be posted as an upgrade now. This either means the latest version of python is preferably installed in the current user system or a reinstall of the existing software has been carried out.
